PROGRAM:
NAME
hb_standby - issues a failover request to the cluster manager
SYNOPSIS
hb_standby [all|foreign|local|failback]
DESCRIPTION
Warning
This command is deprecated. It is only suitable for legacy Heartbeat clusters without
Pacemaker enabled. In Pacemaker-enabled clusters, the crm(8) shell supports switching
individual nodes into standby mode, and replaces hb_standby.
/usr/share/heartbeat/hb_standby issues a request to the cluster to move resources from the
node where it is invoked, to the other node (if it is currently available). The meaning of
the options is relative. This manual assumes the following configuration to be present in
/etc/ha.d/haresources:
alice drbddisk::r0 Filesystem::/dev/drbd0::/local/groups::ext3 10.0.0.1 smb
bob drbddisk::r1 Filesystem::/dev/drbd1::/local/ldap::ext3 10.0.0.2 ldap
OPTIONS
The following options are supported:
local
Migrates any resources that the local node is the preferred node for.
When invoked on alice, Samba would be shut down, the IP address 10.0.0.1 would be
released, /local/groups would be unmounted, /dev/drbd0 would be placed into the
secondary role and bob would take all these services over.
When run on bob, OpenLDAP would shut down, 10.0.0.2 would be released, /local/ldap
would be unmounted, /dev/drbd1 would be placed into the Secondary role and alice would
take over all these services.
foreign|failback
Migrates any resources that the local node is not the preferred node for.
When run on alice, OpenLDAP would shut down, 10.0.0.2 would be released, /local/ldap
would be unmounted, /dev/drbd1 would be placed into the Secondary role and bob would
take over all these services.
When invoked on bob, Samba would be shut down, the IP address 10.0.0.1 would be
released, /local/groups would be unmounted, /dev/drbd0 would be placed into the
secondary role and alice would take all these services over.
all
Migrates all resources to the other node.
Invoking hb_standby without any options is identical to hb_standby all.
CAVEATS
hb_standby is only usable in R1-style configurations (i.e., those configured using the
haresources file).
Use hb_standby online using onworks.net services
